  • Examining Colorado's First-Of-Its-Kind EPR Oil Recycling Program With David Lawes

    Examining Colorado's First-Of-Its-Kind EPR Oil Recycling Program With David Lawes

Read along with this episode.Americans dispose of approximately 1.3 billion gallons of used motor oil annually, but only about 800 million gallons get recycled, and most of that is burned as fuel rather than re-refined into new oil. The plastic packaging oil comes in is more problematic: most curbside programs won't accept them because residual oil contaminates other recyclables. What happens when the companies that make motor oil embrace extended producer responsibility (EPR) laws that require recycling the oil and the containers it comes in? David Lawes, CEO of the Lubricants Packaging Management Association (LPMA), is leading what could become a national model for extended producer responsibility. Colorado just became the testing ground. In September 2024, five major oil companies—BP Lubricants, Chevron, ExxonMobil, Shell, and Valvoline—founded LPMA as an independent producer responsibility organization.

    Colorado gave producers a choice: join the Circular Action Alliance, which manages all packaging and printed paper recycling in the state, or develop their own sector-specific program that demonstrates better outcomes. LPMA chose the independent path, arguing that petroleum packaging requires specialized handling that general-purpose programs can't provide efficiently. Lawes brings two decades of EPR policy experience to the role, including a decade regulating EPR programs in Canada. The program he ran in British Columbia achieves a 96% recycling rate for oil containers—compared to less than 1% in most U.S. states. "This is not about skirting the law or finding an easier pathway," Lawes explains. "It is about meeting the same results in an industry-friendly way."If Colorado's model works, it could reshape EPR programs nationwide. We discuss why petroleum packaging can't be managed through curbside programs, what lessons from Canada's more developed EPR system apply here, and whether the U.S. needs national recycling standards to harmonize the patchwork of state regulations.

  • Star's Tech Hando Choi On Inventing A Low-Carbon, Low-Chloride De-Icer Made From Star Fish

    Star's Tech Hando Choi On Inventing A Low-Carbon, Low-Chloride De-Icer Made From Star Fish

    Read along with our transcript.

    What if the solution to winter's infrastructure corrosion and environmentally benign home sidewalk de-icing was an invasive starfish being thrown back into Korea's coastal waters? Hando Choi, president of Star's Tech, joins the conversation to explain how one region's invasive species problem can become another's environmental breakthrough. The company developed ECO-ST, a de-icing product made from starfish skeletons that not only melts ice faster than conventional rock salt but also reduces the chloride pollution that causes billions of dollars in damage to roads, bridges, and vehicles every winter.

    Meanwhile, in Korean waters, the Northern Pacific sea star has become such a menace to shellfish aquaculture that the government purchases 3,000 to 4,000 tons annually to control populations. Stars Tech upcycles about 10% of that collected material, extracting the porous calcium carbonate structures that give starfish their shape and their remarkable ability to store and release chloride. The technology began as a high school science project when founder and chief scientist Seungchan Yang experimented with natural pore structures to control ion release, eventually connecting that research to the negative impacts of conventional deicers while studying at Seoul National University.

    The economic case is compelling once you factor in the full cost of ownership. While ECO-ST runs $465 to $650 per ton compared to $100 to $150 for commodity rock salt, salt itself accounts for less than 5% of most winter maintenance budgets. The Isaac Walton League of America estimates that infrastructure damage from road salt ranges from $30 to $300 per ton used. Stars Tech's simulations based on U.S. municipal data show ECO-ST can deliver up to 5,000% ROI over time when lower infrastructure maintenance costs, fewer reapplications, and ESG compliance benefits are factored in.

    ECO-ST is available on Amazon in the U.S. and Canada, with retail partnerships launching this winter. You can learn more about Stars Tech at starstech.co.

  • Liquidonate CEO Disney Petit On Solving The Retail Returns Crisis

    Liquidonate CEO Disney Petit On Solving The Retail Returns Crisis

    What if the solution to the retail industry's $890 billion returns crisis wasn't better logistics, but better logic? Disney Petit, founder and CEO of Liquidonate, is proving that the most sustainable return skips the trip back to a warehouse and goes directly to a community in need. Americans returned nearly 17% of all retail purchases last year, generating 2.6 million tons of landfill waste and 16 million tons of CO2 emissions. Each return costs retailers between $25 and $35 to process, yet 52% of consumers admit to participating in return fraud at least once. Petit witnessed this broken system firsthand as employee number 15 at Postmates, where she built the customer service team and created Civic Labs, the company's social responsibility arm. Her food security product Bento, which allowed people without smartphones to access free food via text message, won Time Magazine's 2021 Invention of the Year Award. Now Liquidonate has earned recognition as one of Time's Best Inventions of 2025.

    Liquidonate integrates directly with retailers' existing warehouse and return management systems. When a product comes back and can't be resold—open box, slightly damaged, or simply unwanted—the platform automatically matches it with a local nonprofit or school that needs it. "It's the same reverse logistics workflow they already use," Petit explains. "It's just redirected toward community good instead of going to the landfill." The platform handles everything: shipping labels, pickup coordination, and tax documentation so retailers can write off donations. Retailers recover logistics costs through tax benefits while communities receive quality products, and millions of pounds of goods stay out of landfills.

    To date, retailers using Liquidonate have diverted over 12 million items from landfills, working with more than 4,000 nonprofits across the country. Liquidonate also tackles return fraud by eliminating "keep it" returns, when customers claim they want to return something but are told to keep the item and still receive a refund. "One hundred percent of the time we're producing a shipping label for a nonprofit who wants that product," Petit says. "We completely eliminate that keep-it return option, so we eliminate the returns fraud option." With $900 billion worth of inventory potentially available for redirection, Petit approaches the business through the lens of environmental justice, building a for-profit company designed to prove that doing good and doing well aren't mutually exclusive—they're interdependent.
